Learning Objectives

The aim the course is to provide the required elements for understanding the foundations of the learning problem, with respect to the main algorithms for regression and classification. In particular, the course aims at enabling:
1. To gain basic notions, foundations, and methodologies of automatic learning, both supervised and unsupervised. 
2. To acquire adequate theroretical and applicative instruments typical of the field of machine learning. 
3. To achieve skills for applying tools and methodologies to different problems and scenarios. 
4. To obtain knowledge and competencies for using and adapting state of the art software systems for the solution of automatic learning problems.

Learning Achievements (Dublin Descriptors)

Knowledge and understanding

at the end of the course, the student will learn: the foundations to understand automatic learning problems, the design and analysis of the main supervised and unsupervised learning algorithms.

Applying knowledge and understanding:

the student will be able to understand the main features of the most common learning problems, and the related techniques for their solution. She/he will also be able to apply this knowledge for designing basic machine learning algorithms and the corresponding software systems.

Making judgements:

the student will be able to determine the adequacy and effectiveness of of machine learning algorithms and methodologies, particularly with respect to regression and classification problems.

Communication skills:

the student will learn to illustrate in a proper way the main learning techniques and to describe the factors affecting their effectiveness, with respect to specific application domains;  in particular, she/he will critically reason through a given mathematical descriptive language introduced during the course.

Learning skills:

at the end of the course, the student will gain a good autonomy level in critically understanding study materials regarding the main issues in machine learning, that will also enable to deal with novel design scenarios to which apply the achieved knowledge.

Teaching, Attendance, Course Books and Assessment

Teaching

Theory lectures and laboratory exercises.

Attendance

Although recommended, course attendance is not mandatory.

Course books

Jeremy Watt, Reza Borhani, Aggelos Katsaggelos: "Machine Learning Refined. Foundations, Algorithms, and Applications", Cambridge University Press, (2020).

Assessment

Learning achievements will be evaluated through a written exam (1 hour long, entailing multiple choice and open questions) and an oral exam.

Evaluation criteria for open questions are: knowledge level, articulation of answers (with the use of examples as well), adequacy level of the explanation, correct use of mathematical notation. Each criterion is evaluated on a four level scale (with equal weight assigned to each criterion). 

The oral exam, which can be taken only if the written exam has been passed (mark greater or equal than 18/30) consists of open questions about the course program. If passed, it determines an adjustement of the the previous mark, thus yielding the final mark. The oral exam is evaluated according to the following criteria: achieved knowledge, understanding of the basic principles of the subject, capability of presenting the topic in a rigorous manner. 

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
